The first major severe weather event of the season resulted in widespread reports of wind damage and large hail.
A pre-frontal trough set off the first round of thunderstorms. One batch formed southwest of the Metro-Detroit area, and another formed in the Saginaw valley and thumb regions. A final round of storms resulted in a squall line along the cold front. The squall line raced to the northeast across the region, and produced numerous wind gusts in the 60-70 mph range. Two tornado warnings were issued. The first was for Huron County, for a supercell that featured an impressive rotation signature on doppler radar. This storm also produced baseball sized hail. The second was issued on a law enforcement report of a tornado in eastern Shiawassee county. Neither warning has been confirmed.
Below is an image of a shelf cloud along the squall line, as it passed over the National Weather Service office in White Lake Township at 7:14 PM.
